[GTALUG] simple plug & play ethernet splitters?

Hi wise folks, I likely found my goal at amazon, say a tp-links unit, but if it is common enough where I could just dance into say a Canada computers, that would be preferred. Basically I seek a simple classic plug and play Ethernet splitter, say with 4 or 5 ports. something that does not require software, even fanless will work. I am hoping once I also find a quality power bar, to connect equipment that is on the other side of my home studio from my desk. Everything I personally use has standard Ethernet ports, with my hoping to set things up once, no removing cables and the like. Am I picturing this correctly, and is there a simple place I can get one inexpensively? Thanks, Karen
